Into the Wild was written by Jon Krakauer. The story is about a young man, McCandless, who changes his name to Alexander. He resided in South Dakota with a man named Wayne Westerberg. McCandless' dysfunctional family is revealed in the beginning. Westerberg tells him many stories of his experiences as a young man and eventually inspires McCandless to camp in the Alaskan wilderness. McCandless searched for edible berries and leaves and would hunt, too. McCandless couldn't handle Alaskan wilderness in the summer and decided to go back. A river had melted stopping from going any further. He was forced to eat wild potatoes until they grew to tough to consume. McCandless attempted to eat the potato's seeds, but they were poisonous and had very harmful side effects. The side effects caused him to have loss of coordination and starvation. Theory has it that McCandless starved to death.
